Seaweed Siren

CR 13.00 Magical Beast CN Large
This creature's three singing heads sway atop serpentine necks that extend from a bulbous body split by a wide, toothy mouth.

A seaweed siren is a predator that uses false humanlike heads on its upper appendages in order to lure prey. The heads babble nonsense words and fragments of overheard sentences. If spoken to, they respond with words from a similar language. This behavior allows the seaweed siren to creep about under the water with only the heads showing, pretending to be swimming humanoids until it is ready to attack.

False Heads — A seaweed siren's false heads can be severed. To sever a head, an opponent must make a sunder attempt with a slashing weapon targeting the head. A head is considered a separate weapon with hardness 0 and hit points equal to the siren's Hit Dice (typically 16 hp). To sever a head, an opponent must deal enough damage to reduce the head's hit points to 0 or fewer. Severing a head deals an amount of damage to the siren's body equal to the siren's Hit Dice. A siren can't attack with a severed head. A siren with no remaining heads can't use its cacophony ability or its spell-like abilities.

Water Dependency — A seaweed siren can survive out of the water for 1 hour per point of Constitution (typically 22 rounds). Beyond this limit, a seaweed siren begins to suffocate.
